Abstract (en)
[origin: WO9115087A1] Circuit arrangement for telecommunication switching networks preferably telephone switching networks, consisting of exchanges, in which mobile subscribers (MT1-MT9) each have access to an exchange (SC) through radio channels (F1-F9) and stationary subscribers (STa-STo) each have access to an exchange (SC) through cable channels (K1, K2), an individual identification being assigned to each mobile subscriber. Both the mobile and the stationary subscribers (MT1-MT9; STa-STo) are each assigned an individual identification with which the subscriber answers (identification signal) and is thereby identified and localized by the exchange (SC). The exchange (SC) then assigns a pair of communication channels to the subscriber (MT1-MT9) to establish a connection between the subscriber and the exchange (SC) or vice versa. The mobile and stationary subscribers have access to the same exchanges (SC) and the accesses of the stationary subscribers (STa-STo) pass through broad-band cables (K1, K2), preferably glass fibre cables, which run directly to the subscribers. The cables extend over the entire distance between the exchanges (SC) and the stationary subscribers without intermediate sub-exchanges and individual wire connections, and the same signalization (identification signal), channel allocation (pair of communication channels) and news transmission as between the exchange (SC) and the mobile subscribers (MT1-MT9) connected to it is carried out through the cables so that each subscriber, whether mobile or stationary, is reached from each exchange (SC) in the same manner through a through pair of continuous communication channels. To reach all subscribers, the number of pairs of communication channels provided is no greater than that necessary for the expected volume of traffic in the corresponding region.
